1TB Upgraded to 5TB (lightroom)

My LR storage was upgraded from 1TB to 5TB last year.

I am currently using 1.3TBs of 5TBs with 3.7TBs free.

I recently demoed Illustrator and then removed it.  After removal, my LR continued to show 3.7TBs free, but now Creative Cloud shows I have over 300GBs in storage.

I engaged in a discussion with Adobe support, and regrettably, as is customary, the organizational coherence within the corporate structure appears to be severely lacking. Adobe support indicates an apparent discrepancy, asserting an exceeded limit, yet Lightroom (LR) persists in provisioning 5TBs of storage. Is this a recurrent stratagem where Adobe entices users with features only to subsequently coerce them into upgrading? My confidence in Adobe's competence and the security of my file storage has been eroded. Despite maintaining backups, I am actively disengaging from Adobe services. I can securely store images across multiple platforms at a significantly reduced cost compared to Adobe's offerings.

In my interaction with Adobe, I was routed through four distinct engineers, none of whom demonstrated a discernible understanding, even when presented with accompanying visual evidence. It appears as though their support script is fundamentally flawed, incapable of processing information beyond what is explicitly presented to them.

Why is this valuable to me?  I need Adobe to fix the problem they created and explain why they upgraded users from 1TB to 5TB.  So far they have no clue what is going on.
